Saliva helps in the conversion of

Options

A. Disaccharides into monosaccharides
B. Oligosaccharides into polysaccharides
C. Starch into disaccharides
D. Monosaccharides into pentoses

Answer

### Step-by-Step Solution:

1. **Understanding the Role of Saliva**: Saliva is a digestive fluid produced in the mouth that plays a crucial role in the initial stages of digestion.

2. **Identifying the Key Enzyme**: Saliva contains an important enzyme called **amylase**. This enzyme is specifically responsible for breaking down carbohydrates.

3. **Recognizing the Substrate**: The primary carbohydrate that amylase acts upon is **starch**. Starch is a polysaccharide made up of long chains of glucose units.

4. **Understanding the Conversion Process**: The action of amylase on starch results in the breakdown of starch into simpler sugars. The immediate product of this enzymatic action is **disaccharides**.

5. **Selecting the Correct Option**: Given the options:
- A: Disaccharides into monosaccharides
- B: Oligosaccharides into polysaccharides
- C: Starch into disaccharides
- D: Monosaccharides into pentoses

The correct answer is **Option C: Starch into disaccharides**.

### Final Answer:
Saliva helps in the conversion of **starch into disaccharides**.
